Description

4-Ethylaniline-D11 is a deuterated isotopologue of 4-ethylaniline, where eleven hydrogen atoms are replaced with deuterium. This high-purity labeled compound is essential for creating internal standards and tracers in advanced analytical chemistry, ensuring precise and reliable quantitative measurements. It is primarily required by researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing sectors for applications in mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for LC-MS/MS: Used as a quantitative reference standard in liquid chromatography-tandem mass spectrometry for the accurate analysis of aniline derivatives and related metabolites.
• Metabolic Pathway Tracing: Serves as a stable isotopic tracer in pharmacokinetic and drug metabolism studies to elucidate biotransformation pathways.
• Environmental Analysis: Employed in the detection and quantification of ethylaniline contaminants in complex environmental matrices like soil and water.
• Polymer & Material Science Research: Acts as a deuterated monomer or precursor for synthesizing labeled polymers to study dynamics, structure, and degradation mechanisms.
• NMR Spectroscopy Solvent & Reagent: Provides a non-interfering deuterium background or acts as a shift reagent in nuclear magnetic resonance experiments.
• Quality Control & Method Development: Critical for developing and validating robust analytical methods in regulatory and industrial QC laboratories.
